ios - import swift class in objective-c, <myModule>-Swift.h file not found -

-

i have ios project written objective-c. created swift class in project, bridging header file accessing objective-c in swift generated successfully, , works fine.

my problem other way around. want import swift class in objective-c code.

in xcode, target -> build settings--> swift compiler section, see objective-c generated interface header name field value mymodule-swift.h , when import header in objective-c class:

#import "mymodule-swift.h"

i compiler error:

mymodule-swift.h file not found

and in project, cannot find file either. how can solve problem?

my xcode version 6.4

  1. go to
    build settings->objective-c generated interface header name
    and set value yourmodule-swift.h (this set, filename need import on .m file #import "yourmodule-swift.h"

  2. go build settings , search "defines module", set both values yes

  3. create class in swift prefix of @objc example
    @objc class myswiftclass{...}

  4. go window->projects , press delete button on "derived data"

  5. build project again

  6. should work now.

why add @objc?

a swift class or protocol must marked @objc attribute accessible , usable in objective-c.

this @objc prefix, tells compiler generate swift class header file. add "mymodule-swift.h" file, example:

@objc class mycustomviewcontroller : uiviewcontroller {..}

will generate code:

swift_class("_ttc10mycustomviewcontroller4viewcontroller") @interface viewcontroller : uiviewcontroller - (void)viewdidload; - (void)viewdidappear:(bool)animated; - (void)didreceivememorywarning; - (swift_nullability(nonnull) instancetype)initwithnibname:(nsstring * __nullable)nibnameornil bundle:(nsbundle * __nullable)nibbundleornil objc_designated_initializer; - (swift_nullability(nonnull) instancetype)initwithcoder:(nscoder * __nonnull)adecoder objc_designated_initializer; @end

allowing objective-c know class.

i'm trying apply flex button on firefox i'm having problem on chrome doesn't happens. this css: .button { display: inline-flex; align-items: center; } as can see in fiddle, "caret" word moved new line, happens if element <button> tag, <div> works expected. http://codepen.io/anon/pen/xblmgx is firefox bug or there css i'm missing? nevermind, looks "mr firefox" doesn't idea... <button> not implementable (by browsers) in pure css, bit of black box, perspective of css. means don't react in same way e.g. <div> would. this isn't specific flexbox -- e.g. don't render scrollbars if put "overflow:scroll" on button, , don't render table if put "display:table" on it. stepping further, isn't specific <button> . consider <fieldset> , <table> have special rendering behavior: data:text/html,<fieldset style="d
