ios - Error running pod install with swift -

-

i new swfit , cocoapods. followed instruction cocoapods

below podfile: 

platform :ios, '8.2'  pod 'swiftyjson', '~> 2.1' pod 'swiftspinner', '~> 0.6' pod 'alamofire', '~> 1.1' pod 'superrecord', '~> 1.2' pod 'toucan

when did pod install got following error: 

 pods written in swift can integrated frameworks; feature still in beta. add `use_frameworks!` podfile or target opt using it.

please ?

updated:

below console log:

$ pod install analyzing dependencies downloading dependencies installing alamofire (1.1.4) installing superrecord (1.2) installing swiftspinner (0.6.0) installing swiftyjson (2.1.3) installing toucan (0.2.0) [!] pods written in swift can integrated frameworks; feature still in beta. add `use_frameworks!` podfile or target opt using it.

add "use_frameworks!" podfile because:

because apple doesn't let build static libraries contain swift. unlike objective-c, apple doesn't ship swift standard runtime libraries ios. decouples language version platform version. when build app swift, you're responsible ship them. default, xcode uses swift-stdlib-tool handle copying swift runtime dylibs, tooling falls short when attempting ship frameworks use swift app objective-c only. app executable , frameworks ship use same set of dylibs, embedded frameworks subdirectory of application bundle.

first, that's because can't link against different versions of standard libraries. furthermore desirable embed them once , not multiple times, because of constraints memory size , network speed, relevant distribution. can make cocoapods integrate project via frameworks instead of static libraries specifying use_frameworks!. if that's not present, won't able integrate dependencies, if depend on pod includes swift source code.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
