Previously we would automatically pick up an Info.plist file copied using any of the CP_* keys, and both move it to the correct location (when belonging to target built) or ignore it, if we were copying it from an imported target.
To simplify the logic in the build system, it is however better to be explicit about this, also because we could actually want an Info.plist file among our copied files.
This was done using search and replace. Presumably it should be done in Xcode so that it can adjust the xib for the new deployment target, otherwise what is the point of storing deployment version in the xib and provide it as a command line argument to the xib compiler as well (only to get a warning if the versions do not match)?
It’s not feasible to maintain the old-style xib translations while we work on the UI. We’ll soon move fully to constraint-based layout which should allow translations to be purely string-based.
