Internal Apps Can Be Beautiful Too

A walkthrough of My Jenkins internal app I built to help improving our build and test cycle and how internal apps can benefit from the same quality and effort given to our production apps. This also uses an internal Vapor service to improve the communication between the app and the Jenkins server. This was given as a Lightning Talk at iOSDevUK 2018.

Stage 2: Improve Jenkins Add parameters to Jenkins The branch (String) parameter Allow any branch to be built The configuration (Choice) parameter Pass selection into Fastlane Update the Fastfile to use correct configuration How to reduce the feedback cycle Introducing the Sample App Match the bundle identifier to Main app Custom Fastlane Actions to automate the work Matthew Gallagher © Sky UK, September 2018
5. Stage 3: Cleaner API Jenkins API: (495 characters) /api/json?tree=jobs[name,description,url,color,actions[parameterDefinition s[description,name,type,choices,defaultParameterValue[name,value]]],health Report[description,score],nextBuildNumber,queueItem[*],lastBuild[number,id ,fullDisplayName,timestamp,duration,estimatedDuration,result,building,queu eId,artifacts[*],actions[causes[userId,userName],parameters[*],lastBuiltRe vision[SHA1]]],lastSuccessfulBuild[number,timestamp,duration],lastFailedBu ild[number,timestamp,duration], scm[userRemoteConfigs[url]]] My API: (13 characters) /api/ios/jobs Matthew Gallagher © Sky UK, September 2018

Stage 4: Resolving problems along the way Problem with Proxy settings using Swift on Linux A workaround for now https://github.com/vapor/vapor/issues/1723 Authentication Currently have Azure Active Directory working well https://docs.microsoft.com/en-us/azure/active-directory/develop/v1-protocols-oauth-code Store keys securely Going to look into Vault and create a Swift wrapper https://www.vaultproject.io Matthew Gallagher © Sky UK, September 2018
8. Stage 5: Design iterations Matthew Gallagher © Sky UK, September 2018
9. Stage 6: Further requirements ✅ Accessibility (Dynamic text, Voice over) ✅ Git branch selection (filtering, scopes) ✅ Allow running builds to be cancelled ✅ Allow failed builds to be re-tried ✅ Expand access to other team members (BA, PO) ✅ Different error states ✅ Send push notification when build succeeds Allow access to other Sky teams Report build issue from within the app Matthew Gallagher © Sky UK, September 2018
