Intellij Gradle debug Cannot resolve constructor 'new groovy.lang.GroovyClassLoader(_$_23parentLoader)' error

While using IntelliJ IDEA Community Edition for debugging my Gradle task, at some point I needed to evaluate expression to see what is current state of the project.

When I type expression and hit to evaluate button, result area displays an error message

Cannot resolve constructor 'new groovy.lang.GroovyClassLoader(_$_23parentLoader)'

In order to fix that, I change expression language from Groovy to Java.

For workaround this bug, you need to revert back this language change. Also you may see this warning: "You cannot proceed any further without agreeing to the Terms of Use for Online Services"

Android Studio 3.0, Intellij IDEA 2017 klavye kısayol problemi

Mac kullanıcısı olarak normalde "cmd+." olarak kullandığınız "comment with line comment" Android Studio 3.0 ile çalışmıyor mu? Bunun sebebi Intellij IDEA 2017.1 ile gelen bir bug. Keyboard layoutları için yapılan bir geliştirme var (bundan sonra comment line shortcut'ı Türkçe-Q layout'u için cmd + shift + 7 olarak güncellenecek, ancak bug yüzünden olamıyor)

Mac cihazınızda bu problemi aşmak için yapabileceğiniz;

Help -> Edit Custom Properties diyerek açılan idea.properties dosyasına şu satırı eklemeniz :

com.jetbrains.use.old.keyevent.processing=true

Sonrasında idea'yı restart ederek "CMD + ." kısayolunu "comment with line comment" kısayolu için kullanmaya devam edebilirsiniz.

How to solve macOS wifi speed fluctuation, low speed problem?

There may be a too many reason but for me, unknowingly, reason is mDNSResponder daemon.

On macOS Sierra version 10.12.4 (I faced same problem El Capitan, too), when I download something in high speeds, sometimes speed drops to 0kbps and after few seconds it starts to download in 100mbps again. This fluctuation occurs occasionally but when it occurs it stays until I restart the computer.

The reason behind this problem is mDNSResponder daemon. For resolve issue, you can;

- Open Activity Monitor
- Jump to Network tab (for finding mDNSResponder process easily)
- click on mDNSResponder
- click X button which left of to the info button.(Force process to quit)
- exit from the process using "Force Quit" button

Or, if you are a terminal guy,

ps aux | grep mDNSResponder
sudo kill -9 <pid>

XCode8 iMessage Swift 2.3 dyld: Symbol not found: __swift_getInitializedObjCClass ,Message.appex/../../Frameworks/libswiftCore.dylib

dyld: Symbol not found: __swift_getInitializedObjCClass
Referenced from: derived_path/PlugIns/Message.appex/Message
Expected In: derived_path/PlugIns/Message.appex/../../Frameworks/libswiftCore.dylib
in derived_path/PlugIns/Message.appex/Message

This problem occurs because of the difference of the target swift versions . You need to set swift version same in the both of the main target and imessage extension target.

XCode8 How to use CocoaPod frameworks written in Swift 2.3 (CocoaPods Lagecy Swift)

If you are developing iOS apps with using XCode8 (with Swift 3.x or Swift 2.3) but your CocoaPod project always gets compile error because of your 3rd party targets implemented in Swift 2.3, you need to set SWIFT_VERSION property in build settings to '2.3'.

For dynamic frameworks, this property shown as "Use Legacy Swift Language Version" - Yes, No.

But after every pod update, CocoaPods removes this settings from Pods project and you need to set this settings again, manually.
