Graydon Hoare's advice on diagnosing compile performance, from https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20161031/003410.html

Compilation performance

This document describes a systematic method for detection, isolation, correction and prevention of regression, on matters of compiler performance. The method focuses on the creation of small end-to-end scaling tests that characterize, and stand in for, larger codebases on which the compiler is seen to perform poorly. These scaling tests have a number of advantages over "full sized" performance-testing codebases:

Core data database cleanup
/*
For example, you use Core Data sqlite.
It is necessary, because sqlite database stores data in single file.
Whole database is single file.
Now you have two options.
1. Delete all data from all tables
2. Delete database sqlite file
Second option is clean but complex.

Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

  • [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
  • [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
  • [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
  • [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.
