Re: [swift-users] Swift migration bug

No worries, since it was related to changing Swift syntax I thought it might end up being in some schema file maintained by the Swift team, thus the original question. :) Easy enough to add it to my list of radars. Sent from my iPhone, please excuse brevity and errors > On Oct 3, 2016, at 3:59

Re: [swift-users] Swift migration bug

Ha, sorry to get to these in the wrong order. The real rule is "is the feature part of the Swift Open Source project", but certainly a normal Xcode user isn't thinking about whether the command they just used "came from Xcode" or "came from Swift". Radars will always get to Apple Swift people

[swift-users] Class Variable delayed stored

I have this class I wrote which stores the error messages from the firebaseauth if a error occurs. The problem is that the variable on first return is not set and on second return is. variable _errorMsg is empty on first return of method registerUser Why is it not storing the variable when it's

Re: [swift-users] Performance critical code in Swift

Thanks for advices! I’m switches to C and will write data to file instead of sqlite It will give me 5x-10x performance growth for writing But it will also increase the time for reading, I think (I've not measured it) I’m also looked for some sqlite alternative, but didn’t found Realm is fast for

Re: [swift-users] Performance critical code in Swift

My general advice for performance critical code (especially when it's about stuff like serialization and parsing): If you just want a working solution without spending much time, stick with C. Swift can be fast, but it's harder to write slow code in C. If, on the other hand, coding time is no

[swift-users] How to change the Swift REPL default prompt?

Hi, I've been using the `swift-mode` and the Swift REPL under Emacs to program in Swift. Unfortunately, the Swift REPL doesn't expect a "dumb terminal" and issues a lot of `ESC` terminal control sequences to format its prompt nicely, e.g. `ESC [J` `ESC [1G ESC[J 1> ESC [1G 1> ESC [1G 1> ESC

Re: [swift-users] CharacterSet vs Set

You are right: I don’t know much about asian languages. How would you go about counting consonants, vowels (and tone-marks?) in the most general way? I think I would need to educate myself about those things. Any pointer welcome. JD > On 3 Oct 2016, at 12:52, Gerriet M. Denkmann

Re: [swift-users] UnsafeMutablePointer on the stack?

Indeed, But that function was just an example. I wanted to learn about how to use the stack to call C functions that will fill some memory area passed as a pointer. Jean-Denis > On 3 Oct 2016, at 09:46, Quinn The Eskimo! via swift-users > wrote: > > > On 3 Oct
