Answer : For iOS, try: var systemVersion = UIDevice.current.systemVersion For OS X, try: var systemVersion = NSProcessInfo.processInfo().operatingSystemVersion If you just want to check if the users is running at least a specific version, you can also use the following Swift 2 feature which works on iOS and OS X: if #available(iOS 9.0, *) { // use the feature only available in iOS 9 // for ex. UIStackView } else { // or use some work around } BUT it is not recommended to check the OS version. It is better to check if the feature you want to use is available on the device than comparing version numbers. For iOS, as mentioned above, you should check if it responds to a selector; eg.: if (self.respondsToSelector(Selector("showViewController"))) { self.showViewController(vc, sender: self) } else { // some work around } Update: Now you should use new availability checking introduced with Swift 2: e.g. To check for iOS 9.0 or later at

Answer : Try if NOT "asdf" == "fdas" echo asdf Use NEQ instead. if "asdf" NEQ "fdas" echo asdf I know this is quite out of date, but this might still be useful for those coming late to the party. (EDIT: updated since this still gets traffic and @Goozak has pointed out in the comments that my original analysis of the sample was incorrect as well.) I pulled this from the example code in your link: IF !%1==! GOTO VIEWDATA REM IF NO COMMAND-LINE ARG... FIND "%1" C:\BOZO\BOOKLIST.TXT GOTO EXIT0 REM PRINT LINE WITH STRING MATCH, THEN EXIT. :VIEWDATA TYPE C:\BOZO\BOOKLIST.TXT | MORE REM SHOW ENTIRE FILE, 1 PAGE AT A TIME. :EXIT0 !%1==! is simply an idiomatic use of == intended to verify that the thing on the left, that contains your variable, is different from the thing on the right, that does not. The ! in this case is just a character placeholder. It could be anything. If %1 has content, then the equality will be fals

Answer : After upgrading to Angular 9 (released today), I ran into this issue as well and found that they made the breaking change mentioned in the answer. I can't find a reason for why they made this change. I have a material.module.ts file that I import / export all the material components (not the most efficient, but useful for quick development). I went through and updated all my imports to the individual material folders, although an index.ts barrel might be better. Again, not sure why they made this change, but I'm guessing it has to do with tree-shaking efficiencies. Including my material.module.ts below in case it helps anyone, it's inspired off other material modules I've found: NOTE : As other blog posts have mentioned and from my personal experience, be careful when using a shared module like below. I have 5~ different feature modules (lazy loaded) in my app that I imported my material module into. Out of curiosity, I stopped using the shared module and

Answer : is this safe enough to naively call chrome.tabs.executeScript every time the extension icon got clicked? In other words, is this idempotent? Yes, unless your content script modifies the page's DOM AND the extension is reloaded (either by reloading it via the settings page, via an update, etc.). In this scenario, your old content script will no longer run in the extension's context, so it cannot use extension APIs, nor communicate directly with your extension. is there a similar method for chrome.tabs.insertCSS ? No, there is no kind of inclusion guard for chrome.tabs.insertCSS . But inserting the same stylesheet again does not change the appearance of the page because all rules have the same CSS specificity, and the last stylesheet takes precedence in this case. But if the stylesheet is tightly coupled with your extension, then you can simply inject the script using executeScript, check whether it was injected for the first time, and if so, ins

Answer : Problem is in space between selectors: .panel-heading [data-toggle="collapse"]:after ^------- // remove this space to make this selector work Now you are selecting all elements having data-toggle attribute which are descendants of .panel-heading . It should be: .panel-heading[data-toggle="collapse"]:after .panel-heading { position: relative; } .panel-heading[data-toggle="collapse"]:after { font-family: 'Glyphicons Halflings'; content: "\e072"; /* "play" icon */ position: absolute; color: #b0c5d8; font-size: 18px; line-height: 22px; right: 20px; top: calc(50% - 10px); /* rotate "play" icon from > (right arrow) to down arrow */ -webkit-transform: rotate(-90deg); -moz-transform: rotate(-90deg); -ms-transform: rotate(-90deg); -o-transform: rotate(-90deg); transform: rotate(-90deg); } .panel-heading[data-toggle="collapse"].c
