Sometimes when you transfer your project to another computer and especially when you create a new developer certificate in the progress, you’ll run into difficulties. When you try to run your app on a device, Xcode will throw the following error:

Code Sign Error: Provisioning Profile '###ID###' can't be found.
The problem is that in your project’s project.pbxproj file the old provisioning profile identifiers are still lingering. You need to clean up that file so that Xcode can build your project without errors.

Here’s how you do that:

1. Close Xcode
2. Right click on your project’s .xcodeproj bundle to show it’s contents.
3. Open the .pbxproj file in a text editor of your choice (make a backup copy first if you feel paranoid)

iOS CRASH SYMBOLICATION INSTRUCTIONS

Not ideal, but works.

1. Copy .app, .dSYM and .crash file into a temp folder
2. Copy the relevant crash symbols into a txt file name 'symbols.txt'. Format should look like:

0x00110176 0xb8000
0x0011003a 0xb8000
0x001d2d44 0xb8000
