Ionic Cordova project returns error while creating and updating ios

Question

I am running an ion project v1 and I recently upgraded my version of cordova-ios to 4.5.0. My cordova, node and ionic versions are as follows

cordova version 6.4.0 node version 6.9.0 ionic version 1.7.15 cordova-ios 4.5.0

Every time I run this ionic build ios , I get an error

 Error: cordovaProject.projectConfig.getFileResources is not a function 

And every time I run this ionic platform update ios , I get this error

 mv: no such file or directory: /{PROJECT_PATH}/platforms/ios/Loanstreet Partners.xcworkspace/xcshareddata/xcschemes/__PROJECT_NAME__.xcscheme 

Boredly thought about what step to take this to fix it. Any help was appreciated.
