Re: [swift-users] Improving compilation times?

Thanks for that link, used it to track down the worst compile time offender: This piece of code: public func logAddrInfoIPAddresses(_ infoPtr: UnsafeMutablePointer) -> String { let addrInfoNil: UnsafeMutablePointer? = nil var count: Int = 0 var info: UnsafeMutablePointer = infoP

Re: [swift-users] Improving compilation times?

Yes, it's best to avoid concatenating strings with +. Not only for performance reasons, but it's also less readable than string interpolation: str += "No: \(count), HostIp: \(clientIp ?? "?") at port: \(service ?? "?")\n" > On 23 Mar 2017, at 08:11, Rien via swift-users wrote: > > Thanks for t

Re: [swift-users] Improving compilation times?

Hi Mark, Thanks for the answer, its great to know that somebody is working on it! I tried to add the -Xfrontend -debug-time-expression-type-checking in Xcode in the Other Swift Flags section but that gives me an error when compiling :0: error: unknown argument: '-debug-time-expression-type-check

Re: [swift-users] Improving compilation times?

Just tried it, did not work on the command line either, though with a simple message “build commands failed” The following command line however does work: xcodebuild -scheme Swiftfire clean build OTHER_SWIFT_FLAGS="-Xfrontend -debug-time-function-bodies" | grep .[0-9]ms | grep -v ^0.[0-9]ms | s

Re: [swift-users] Improving compilation times?

Rien, You can also add the flag -Xfrontend -warn-long-function-bodies=100 directly to Other Swift Flags in Xcode. Xcode will then generate warnings for each function that compiles more than the specified amount of time (milliseconds) you supplied in the parameter (100 in this case). Regards, Piot

[swift-users] type casting for Dictionaries keys

Re: [swift-users] type casting for Dictionaries keys

It's because AnyHashable is not an existential like Any but a value type (I believe it was a struct) which erases the type restriction from your Hashable type. Simply look up AnyHashable. -- Adrian Zubarev Sent with Airmail Am 23. März 2017 um 12:07:16, Седых Александр via swift-users (swi
