Xcode


XcodeHow does it see profiles?



CODE_SIGN_IDENTITY = "iPhone Developer";



CODE_SIGN_IDENTITY = "iPhone Developer";PROVISIONING_PROFILE = "";





CODE_SIGN_IDENTITY = "iPhone Developer: Jay Graves (E6L876QFM6)";



CODE_SIGN_IDENTITY = "iPhone Developer: Jay Graves (E6L876QFM6)";

PROVISIONING_PROFILE = "0FEB5831-22D3-4B1D-A973-59ED243E8103";

What does all this mean?


•Automatic Profiles•Good if you don’t have multiple projects.•It can select the wrong profile.•Rules on automatic selection are not defined.



•Automatic Profiles•Good if you don’t have multiple projects.•It can select the wrong profile.•Rules on automatic selection are not defined.

•Specific Profiles•Much more control over which profile is selected.•Can be a pain to update the project file every time a profile is updated.





Scenario


Scenario1 Project 2 Builds


Multiple Build ScenarioPossible Solutions


•Add a Duplicate Target



•Add a Duplicate Target•Large project file change



•Add a Duplicate Target•Large project file change•Duplicated all of the Configurations



•Add a Duplicate Target•Large project file change•Duplicated all of the Configurations•A 2nd info.plist has been created.







• Add a new Configuration




• Add a new Configuration•Still a large project file change




• Add a new Configuration•Still a large project file change•Still duplicated all the build options




• Add a new Configuration•Still a large project file change•Still duplicated all the build options•Easy to forget new build options



Multiple Build ScenarioA better solution
