ios - How to perform different segue based on condition from a button click in swift? -


i'm building app in button takes profile registry view if open app first time , if open app other time. how can accomplish programmatically, have seen connects button 1 view.

@ibaction func nextviewcontroller(_ sender: uibutton) {     if launchedbefore  {         print("not first launch.")      } else {         print("first launch, setting userdefault.")           userdefaults.standard.set(true, forkey: "launchedbefore")     } }

i think, trying connect button perform segue multiple viewcontroller right?? not possible

instead have connect segue between view controllers

adding segue between 2 viewcontrollers:

from interface builder, ctrl + drag between 2 viewcontrollers want link. should see:

enter image description here

and based on condition should perform segue identifiers below:

@ibaction func nextviewcontroller(_ sender: uibutton) {             if launchedbefore  {         /*use identifier given in story board*/                self.performsegue(withidentifier: "othervc", sender: self)              } else {     /*use identifier given in story board*/         self.performsegue(withidentifier: "register", sender: self))                 userdefaults.standard.set(true, forkey: "launchedbefore")             }         }

for more descriptive answer segue see answer how connect 2 view controllers 1 button in storyboard?

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
