But - I really wonder why XCode so often compiles the whole stuff (about 1.800 files in Deployment mode, still half of them in Development Native mode) when only one or two files have been changed. And I am aware of relations of base source files which are included in almost everything. The changed files are rather kind of branch source files, thus they should not effect many other files.
Are there no cashing options for XCode in order to check which files really need to be re-compiled? Or do I have to set a checkbox I could have forgotten to check?
The most common reason for this is that if your precompiled headers change, then every source file needs to be recompiled with the new precompiled header.
And the precompiled header is rebuilt if a) any header in it changes or b) any compiler setting that affects precompilation changes.
If you have a case where you truly just changed one source file and it wrongly causes other sources to be rebuilt, please file a bug and provide us as much information as you can about the nature of the change to the source file.
