Possibly basic question but I'm not sure where to begin for an answer. I am very much a newbie to Xcode, Cocoa, Swift and Objective-C.
I'm interested in developing an open-source Markdown editor for the Mac that will build from existing open-source code. I have gone to GitHub to download the source code for two existing projects, MacDown and WriteDown! For both projects I download the project .zip file (and am happy that the button to do so is now easily available), and extract the .zip file's contents on my hard drive. In each project there is an .xcodeproj file which I open up in Xcode... and I see tons of errors, mostly because of things that are missing, so I cannot build and run them.
With WriteDown I see "missing base SDK" (and get a corresponding error when I try to run it), and many other files missing (frameworks, products, and "pods"). With MacDown I get a lot of errors mentioning missing pod files.
If it were just the one project that gave me errors I would assume this was something specific to that project, but since they're both giving me errors it sure seems like I'm doing something wrong in general. Should I be downloading something other than the downloadable zip? Downloading extra frameworks? Taking an extra step in between?
I am using Xcode 6.1.1 on OS X 10.9.5, which MacDown seems to indicate it's compatible with.
Few things:
1) If an .xcworkspace is available, you should open that in lieu of the .xcproj. The workspace contains multiple projects that are important for the building of the application.
2)
Check out this answer for "Missing Base SDK" XCODE Base SDK Missing
3) Go to /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs and check to make sure you have the proper system SDKs available
4) It looks like those projects also require CocoaPods, a OS X Dependency Manager. You need to download the "pods" AKA 3rd party dependencies in order to build the application

I'm completely new to macOS development, this might sound quite basic.
I need to distribute a Golang app for macOS.
I built the Go executable for macOS, the executable works fine on macOS.
I made its .app structure following this tutorial
But before distributing it, I need to do a few things like code signing & integrating Sparkle (for updates).
For that, I need to open this .app as a Xcode project. How do I do that ?
Xcode recognizes .xcodeproj extension
I created a sample Xcode Objective-C project but how do I get this project to run my executable/.app ?
You do not need to open the app as an Xcode project - that doesn't make sense as such and cannot be done, as the app is not an Xcode project.
I would suggest instead using the gon tool you can find here for code signing.
The easiest way to install it is usually through HomeBrew by running:
brew tap mitchellh/gon
brew install mitchellh/gon/gon
The above requires you to have HomeBrew installed in advance.
After installing, you create a config.json file as described on the gon GitHub page, and then run:
gon config.json
That will sign, zip, notarize and staple your application for you - creating a .dmg file for distribution.
In regards to Sparkle for easily updating your program, this is something you have to integrate into your Go program. You can find an example of how to do that here.
The example contains a simply Objective-C function sparkle_checkUpdates() that uses the Sparkle framework to invoke the updating mechanism. It also contains a Go function sparkle_checkUpdates() that use C imports to call that C function described before.
In your existing Go program, you just need to call that sparke_checkUpdates from somewhere when the user wants to check for updates.
I downloaded this Xcode project(version 1.0 as in contents.xcworkspacedata) from here
When I try to open it, got this error:
Failed to load project at '.../Lesson31_OSXCocoa/Lesson31_OSXCocoa.pbproj', incompatible project version.
How do I open project version 1.0 with xcode 4.2?
You're better off trying to find a newer tutorial, or just studying the code as-is, without expecting to build and run it.
Judging by the modification dates, this code is almost ten years old. Even if you can get a modern version of XCode to open it, there's no reason to think that the headers, libraries, etc., that it needs to compile and run will still be compatible. Moreover, ten years is a long time in software terms. While some of the content might still be applicable, it certainly won't be anywhere near the cutting edge (which itself won't be new by the time you've mastered it).
All that said, if you're really intent on working with that project file in XCode 4.2, the best way is probably to convert it the same way a continuously developed project would have: XCode by XCode.
You can download older versions of XCode from Apple here (requires free Apple developer account).
Some older version will be able to import that file and update it to a newer format.
Assuming you don't stop at that point and use that version of XCode, you can repeat the process with the updated project file and ever-newer versions of XCode until you've arrived at version 4.2.
Relatively easy to make a new project and add the appropriate files to it. Took less than 10 minutes (had to update the code in a few places). Note that I didn't spend much time cleaning up this old code - quite a few deprecated warnings. But it runs and works. I have Xcode 4.3.2 installed but hopefully you'll be able to open it with 4.2. Here's a link to it: Lesson31.zip
Note that the process for doing this (so you can do it for any others), is to create a new Mac OS X Cocoa Application project, add the files (except main.m) from the old project to the new project, and then add necessary libraries to fix link errors (OpenGL Framework). If there's a nib then you can open that in Xcode and copy the window with view and controller out of that project and paste them into the .xib file created with the new project. Then fix compiler warnings/errors as necessary (add a few (char*) coerces, remove reference to std::ios::nocreate which doesn't seem to be available, etc).
I'm trying to use the GData framework, so I downloaded it and it came as an Xcode project so I assumed I needed to build it. So I opened it up and and clicked run and it compiled fine, but where do I go to access the .framework it created? I'm new to frameworks and have only been using xcode for a month or two so you'll have to excuse my lack of knowledge about it.
The documentation will help you
Anyway, by default the target is GDataUnitTest, just change it to GDataFramework. Once you compile it you will find the framework in the folder of the XCode Project called target.
I am tryingo to build a GUI application using the JUCE framework on MAC OSX.
I have dowloaded all the API's and got a small hello World program running fine.
However, when I add files to my Xcode project I get compilation errors that say that the Juce library files don`t exist. I would like to know how to get the library API in the build and link path in XCode so that it finds the neccesary files for compilation.
What I would do on Visual Studio going to properties and adding aditional library dependencies, is what I need to do in XCode but I don't know how.
Any help greatly appreciated.
thanks.
Old question but maybe a useful answer in the future....
If you have the "Hello World" up and runnning, it should already be linked to the library. Are you using the introjucer? This should help get everything up and running for you. If you are, you need to add classes etc to the introjucer, as this sets up Xcode / VStudio for you. If not, (Presuming XCode 3 as you are using leopard) goto Xcode > Preferences. Scroll along to source trees, and add the path to the juce folder in there.
I'm very new to objective-c, xcode, and mac development in general (I
come from a java development background). I'm attempting to integrate
GHUnit into xcode to write some simple unit tests for an objective-c/
cocoa project I've recently been tasked with.
I've attempted to follow the directions here :
http://gabriel.github.com/gh-unit/_installing.html for:
Installing (Mac OS X)
-- Installing in /Library/Frameworks.
I'm working with xcode 3.1.3 running under Mac OS 10.5.8
I have created the new Target "Tests", and Link Binary With Libraries
shows the GHUnit.Framework.
I've added the GHUnitTestMain.m to the project as the directions
describe. However, I get "error: GHUnit/GHTestApp.h: No such file or
directory" for the #import
I looked for this header file in the framework and I don't see it
included. #import is not causing any errors, and I
DO see this file in the framework directories.
Is the downloaded framework and the GHUnitTestMain.m out-of-synch with
each other? or have I missed something in the configuration?
As another note, in the directions:
"If your main target is an application, you will need to include these
source files in the Test project manually."
I don't understand what action is required from this statement. I
have no idea if it's related to my current compilation error.
Thanks for any help in sorting this out.
Make sure you downloaded the OS X version of GHUnit. The github page lists a few downloads for iOS aswell. At the time GHUnit-0.4.26.zip is the latest OS X version.
I encountered the same problem.
You might add the test class to the main application target. Uncheck the target and then, the error "GHUnit/GHUnit.h file not found" disappeared.
