iDevGames: XCode Build Question

"The problem is that if I only change my resources, I have to do a clean,
then a build to get the new resources deployed. The project consists of 50
or so source code files, and a build takes more than 30 seconds."

Red Sweater: Xcode Index

"f you use Xcode often, surely you appreciate the “Code Sense Index.” This
is the magic cache of symbolic info that allows tricks like command-double-
clicking a variable name to jump to its declaration, or Opt-Period to complete
a function name. ... Unless. Ughh!!!!! Angst, angst, angst! It’s got crap in the
index."

idevapps.com - My apps don't run anymore!

"Turns out I was using ZeroLink... But I found out that it only happens when
I set it to be the default application to open all .rtf files. If I change only one
file to open with it, it runs perfectly."

[delovski]

I downloaded some demo projects from Apple's site and Xcode complained
it can't find MacOSX10.4u.sdk. I didn't even knew something like that exists
in carbon projects.

I'm not sure exactly what I did to make this error go away - I just followed
what this document told me to do: Building Your Code.

Now, everything is fine again. ;)

First, it was: HISimpleList. It has that MacOSX10.4u.sdk problem, but then
I found another list example: SimpleList. It has issue with stdlibc++.a. Well,
just removing that library from the project solves it.

[Ike]

Carbon List: Is Carbon Viable?

"What I *do* need is better ways to navigate my code. Xcode's Find in Project
feature is an interface and usability disaster, and its Jump to Definition feature
is almost useless to me. These are important pieces of functionality on which
I rely heavily and their implementation in Xcode severely impacts my productivity
and enjoyment level when I'm using Xcode."

adc: Mac OS X Xcode 2.4 Release Notes: Compiler Tools

These notes are for the Mac OS X Xcode 2.4 Release of the compiler tools.
They contain information about the following topics:

The Mac OS X Mach-O GNU-based assemblers
The Mac OS X 32-bit Mach-O static link editor
Mach-O object file tools (nm, otool, and so on)

roobaLog: Just Because it Compiles, Doesn’t Mean it Works

"My question is why doesn’t the compiler whine about me sending 3 arguments
to a C function that only takes 1? I don’t even see a warning. I dug a little
deeper. Turns if you want to see the error, you have to #include<unistd.h>
(that’s where usleep’s prototype is declared). So why does this even compile?"

CocoaDev - XCodeTips

"Enabling Warnings If you'd like to enable as many of gcc's compiler warnings
as possible, there are a few pitfalls to be aware of when doing so with Xcode.
The following is my advice based on my experience."

MachTen - My top reasons why Mac developement with XCode is a nightmare...

"We've been working with XCode on the Mac for at least six month now.
We used to build all our Mac products with CodeWarrior 8.3 and 9 but decided
to drop it because it wasn't offering any support for the new Apple SDKs ...

... XCode uses the well known GCC compiler and all the suite of the GNU
toolchain which would supposedly offer a much better development environment.
I've been quite disapointed with that choice. Here are the main problems we
encountered with XCode"

Uli's blog - The Dangers of ZeroLink

"So, instead of just breaking or just working, ZeroLink can make unlinked
functions half-work. That's a thing to keep in mind... "

[delovski]

I hate this GCC warning: "suggest parentheses around assignment used as
truth value". I know the story behind it but I don't care. Tutorials like to give
very simplified examples, but I don't buy it.

So, putting "-Wall -Wno-parentheses -Wno-unused-variable" as "Other C flags"
did the trick. Now, instead of a few thousand warnings in my project - I have
none. That allows me to turn on treatment of warnings as errors.

P.S. Options to Request or Suppress Warnings

[delovski]

Apple List: Showing all the build settings

"If by "build settings" you actually mean "preprocessor macros," then you're
looking for -dM.

1) Project > Edit Current Target
2) In Build tab, find Other C Flags and add -dM to it
3) Choose your source file and select Build > Preprocess

You'll get a list of all the preprocessor macros defined for the compilation of
that file."

[delovski]

TheList: Change Application Name

Chris Espinosa: "The most common problem is that you have to change the
CFBundleExecutable in the Info.plist to match the new execitable name once
you change the product name. In recent versions of Xcode we set this to be
${EXECUTABLE_NAME} so it's propagated automatically, but in projects cre-
ated with templates from earlier versions, it's set at project creation time and
must be changed manually when the product name is changed."

[delovski]

Because of some 3rd party code I had to change my C flags:

"-Wall -Wno-parentheses -Wno-unused-variable -Wno-unused-function -Wno-unused-label -Wno-trigraphs"

* see: GCC - Options to Request or Suppress Warnings

* see: warning: trigraph ... ignored - again

"The documentation is out of date. -Wtrigraphs has been included in
-Wall for a long time, but no one noticed because it didn't do
anything when trigraphs were disabled. We felt that they were a
common enough portability problem that they should be warned about
even when they were disabled..."

[Ike]

the List: Re: -Wall

"Finally, some versions of Xcode have a bug where you can't turn ZeroLink
off; that means you'll get what looks like a clean compile, but you'll crash as
soon as you try to run. The only way to fix this is to hand edit the project
file to turn off ZeroLink.

1) Find your project file. It ends in '.xcodeproj'. This is a bundle, so you can
either use the terminal and cd into it, or you can control click on it to open it
up (control click -> 'Show Package Contents').
2) ..."

I hate drag&drop in editors!

MF - Xcode cannot find header file?

"I also edit the settings of "Header Search Path" to be /opt/local/include
and type
# include <gsl/gsl_xxx.h>
in my program.
But Xcode2 still cannot locate the file."

Heh: YES!

Just had this issue myself. I had #include <libxml/xmlmemory.h> and Xcode
was not able to locate it. Changing it to <libxml2/libxml/xmlmemory.h> didn't
solve anything. So I had to put libxml2 folder into project settings. At first I
typed "usr/include/libxml2/" into Header Search Paths option, but it didn't
work that way! Correct path is "/usr/include/libxml2/".

MF - A Warning for those of you installing XCode 3 and 4

"If you're going to do this and have XCode 3 installed at the default /Developer,
you'll need to do 3 installs for things to work properly - namely, upgrade
XCode 3 to 4, then install XCode 3 elsewhere, then reinstall XCode 4. If you
do NOT do this, XCode 4 will crash immediately on launch with a plug-in error."

Apple - iTunes was unable to load provider data from sync services

"Thanks. I just ran into this problem after installing the latest version of
Xcode 3.2.6 with the 4.3 SDK."

Usefull flags, when needed:

-Wall
-Wno-parentheses
-Wno-unused-variable
-Wno-unused-function
-Wno-unused-label
-Wno-trigraphs
-Wno-idiomatic-parentheses // if (self = [self init])

High Order Blog: Customizing Xcode File Templates

"One of the first things many users of Xcode want to do is customize the file
templates used to generate stubs for classes and other items in your project.
We’re spending most of our time building iPhone applications, so we’re inte-
rested in customizing the Cocoa Touch templates."

lists.apple.com - Re: recompile without -mlong-branch?

"The Snow Leopard version of the 10.4u SDK seems to contain an outdated
version of crt1.o. You can fix the linker warning on your own by recompiling
the Csu package from the Tiger sources;

Replace /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/crt1.o with the newly
created version."

universalmind - What every iOS Developer Should Be Doing with Instruments

"You've just wrapped up development on a shiny new iOS project and
have done your best to ensure that the app doesn't crash and it seems to
run ok on your test devices, but is it ready to submit? If you haven't done
any profiling in Instruments, the answer is probably no. Just because it
doesn't crash doesn't mean that it's going to behave and run well on your
user's devices"

so - Using Xcode post-build scripts to create a ZIP archive

"I am working on a super simple little app that I distribute as a ZIP archive.
The archive contains the app itself, a readme, and a few scripts. I wanted to
automate this process, so I added the scripts to my project and auto-copied
them into the build folder with a copy files build phase."

[delovski]

lists.apple.com - Re: Not finding libraries

"I've sometimes seen a problem where Xcode thinks a '.a' file is a dynamic
library, which causes the linker to ignore it. You can fix that by changing the
file's type to 'Mach-O Object Code' in the file inspector in the right-hand pane."

wikihow.com - How to Make a DMG File on a Mac

"One way to store or group files on a Mac is to create a Disk Image. A Disk
Image is a file which has the properties of a separate hard drive or CD and
allows for greater password protection and compression. It has a size limit
and options for encryption to keep your files safe and secure. While there
are a few applications that perform this task for you, it is recommended
that you complete this process manually."

adf - Porting old Cocoa projects to Xcode 7.3

"I have a number of very old Cocoa projects, created before Xcode using
Project Builder and Interface Builder. I tried opening these projects in Xcode
7.3 and they wouldn't build -- the projects were too old. Is there another
way to bring them up to date? Can the Interface Builder NIB file be updated
to work in a recent version of Xcode?"

eclecticlight - If you're still running El Capitan, Apple doesn't care about you

adc - Exporting Your Framework Interface

"For ANSI C-based code, you can usually just prefix an underscore character
to the name of a function or variable to get the symbol name. For languages
like C++, which uses mangled symbol names, you may need to run the nm
tool to get the list of existing symbol names. Run nm with the -g option to
see the currently exported symbols. You can then copy the output from the
tool and paste it into your exports file, ..."

Apple's new style documentation is amazing. You can choose Swift or
Objective-C, it is fully functional on an iPhone or iPad and it is crafted and
presented like a work of art. The downside is the usability has fallen off a
cliff. Like you I actually hate the new style documentation.

r - What programs/software do you use aside from Xcode?

"PaintCode is essential for me when doing UI. It is 99$ but isn't hard to find
for free online. Buy it if you can though it is really a great program and always
good to help out the devs."

bitbar How to archive and export ipa from script using Xcode 6

"First, create yourself a build script. The proposed build script could start by a
clean and followed with performing an archive call:"

[delovski]

so - Move to beginning of text in Xcode

"As of 7.3 (not sure when it was added), Xcode seems to have turned this
on by default. Cmd-left in the Key Bindings preference pane is now bound
to Move to Beginning of Text.

Personally, this drives me bonkers, so I've changed it back to Move to
Beginning of Line."

[delovski]

-Wno-idiomatic-parentheses // if (self = [self init])

[delovski]

so - I get conflicting provisioning settings error when I try to archive to submit an iOS app

"Don't forget to do this,

Select the Project -- > Build Settings. Search PROVISIONING_PROFILE and
delete whatever nonsense is there."

For some reason this script DOES work on Mojave/Xcode 10.1

cp ${BUILT_PRODUCTS_DIR}/${EXECUTABLE_NAME} ${PROJECT_DIR}/${EXECUTABLE_NAME}App

For some reason this script DOES NOT work on Mojave/Xcode 10.1

cp ${BUILT_PRODUCTS_DIR}/${EXECUTABLE_NAME} ${PROJECT_DIR}/${EXECUTABLE_NAME}App

Two computers, same project, build phase - run script. Works on one, does not on the other.

BUT THIS!!!!!

cp "${BUILT_PRODUCTS_DIR}/${EXECUTABLE_NAME}" "${PROJECT_DIR}/${EXECUTABLE_NAME}App"

DA - Debugging fails with "Error 1" if hardened runtime is enabled

"I had to edit my scheme settings, and instead of debugging the process as
me, I had to debug process as root. Not sure why this works, but hope it's
helpful."

[Ike]

So, -Wno-unused-but-set-variable did not exist before but if I syncronize
projects with the Github, Xcode will have unrecognized flag warning so
-Wno-unknown-warning-option seems to do the trick

-Wall
-Wno-unused-variable
-Wno-parentheses
-Wno-unused-but-set-variable
-Wno-unknown-warning-option

[Ike]

so - iOS scheme goes missing when I branch my project (Xcode 4.2)

"From my master branch, I exported the schemes I needed - I did by
navigating to Product > Scheme > Manage Schemes... on the Xcode menu.
I then selected the schemes I wanted to export (i.e. Development and
Release in my case). Finally, I chose the Export... option after clicking on
the gear icon as shown in the picture below."

r - FYI - Xcode 15 + iOS 17 Forces network debugging.

"Come to find out on iOS 17 + Xcode 15 Apple is now FORCING developers to
debug over the network. Now installs via Xcode take on average 250% more
time. There is no way to turn this off."

so - How do you change the display format of floats & doubles in Xcode debug window?

"Xcode insists on displaying them using scientific notation, which is a real pain.
I need to see a decimal representation."
