Swift Package Manager and Xcode: saving Xcode settings?

Question

I am developing a server in Swift and am using the Swift Package Manager. And it’s convenient to find it during my development on my Mac OS to create an Xcode project to use Xcode as my IDE (i.e., dependencies between packages change from time to time. I used swift package generate-xcodeproj to execute this is mine the problem occurs at this point. I created some settings in Xcode. For example, I set the DEBUG flag and I have a .plist file that is in the phase of copying files. They get lost when I restore the Xcode project. It seems I can’t just use swift package update , because sometimes files vary depending on, and they do not apply to the Xcode project.

What I would like is a tool that allows you to separately set the Xcode settings in a file outside of Xcode, which can be imported into Xcode when I do the swift package generate-xcodeproj . I have not seen a way to do this.

A related question: when I do swift build , I need the same build settings that will be used.

Suggestions?

Answer 1

I would use a script or makefile to import your settings into the generated Xcode project, every time you regenerate it. You can use xcodeproj rubygem .

See an example script .

Regarding the use of your settings in swift build , can you give an example of such a setting? In general, a makefile can read your settings file and pass the appropriate swift build options.

Based on @ vadim, answer above, here is xcodeproj rubygem solution to the first part of my question:

Answer 3

I can not help with Copy Files Phase .

However, I just played with conditional compilation, for example:

 swift package generate-xcodeproj --xcconfig-overrides Sandbox.xcconfig 

Sandbox.xcconfig

 FLAG_SANDBOX = -DSANDBOX OTHER_SWIFT_FLAGS = $(FLAG_SANDBOX) 

This creates an Xcode project in which SANDBOX is under control.

It can be used in fast code like this

 #if SANDBOX print("sandbox") #else print("production") #endif
