Updated iOS app build instructions

-Still, we use the branch ``central-ios-release-build`` to prepare for the build. We usually merge ``ubilabs--ios--develop`` into ``master`` and then ``master`` into ``central-ios-release-build``. Builds off the latter branch can be tested using [this Jenkins job](https://xmake-mobile-dev.wdf.sap.corp/job/sapsailingprogram/job/sapsailingcapture-OD-darwinintel64_dev-darwinintel64_dev/). Run a [Build with Parameters](https://xmake-mobile-dev.wdf.sap.corp/job/sapsailingprogram/job/sapsailingcapture-OD-darwinintel64_dev-darwinintel64_dev/build?delay=0sec) and enter ``central-ios-release-build`` as the TREEISH. The build should succeed and produce the .ipa file somewhere in the [build's target output](https://xmake-mobile-dev.wdf.sap.corp/job/sapsailingprogram/job/sapsailingcapture-OD-darwinintel64_dev-darwinintel64_dev/ws/gen/out/Exported-IPAs-Release-iphoneos/)

-When the test build was successful, the branch contents need to be merged into the central git repository's branch ``fa/rel-1.x``, e.g., ``fa/rel-1.0``. Pushing immediately to this branch to the SAP-internal git is not permitted by Gerrit rules. Instead, it is necessary to push to ``refs/for/fa/rel-1.x``. Furthermore, the commit to be pushed needs to have a ``Change-Id:`` and a ``CR-Id:`` tag in the commit's comment. The ``Change-Id:`` is produced by a commit hook that can be installed in each developer's local git environment by using the following command:

- <pre>gitdir=$(git rev-parse --git-dir); scp -p -P 29418 d000000@git.wdf.sap.corp:hooks/commit-msg ${gitdir}/hooks/</pre>

-The ``CR-Id:`` is more tricky. For Android at least it seems it may no longer be needed, so you could theoretically use anything for the CR-Id: value. It is produced by the Java Correction Workbench where a Correction Request needs to be created. This can be achieved using [this link](https://css.wdf.sap.corp/sap/bc/bsp/spn/jcwb/default.htm?newCMForProject=sapsailingcapture&newCMComponentName=SV-COE-MSO-CDP) which is also contained in the lower left corner of our [Project Portal Page](https://projectportal.neo.ondemand.com/projects/sapsailingcapture). The correction request shall describe what has been corrected. In our project's context it seems useful to link the correction we're trying to release to a bug in our Bugzilla. For this, select "External" as the "Issue Type" and enter the bug's URL as well as a short text. The "ACH Component" should have been pre-filled and should read ``SV-COE-MSO-CDP``. If not, make sure you enter the text ``SV-COE-MSO-CDP`` and wait for the tool to complete this to "CashDesk Plus" before you press "Next". Ultimately, you will see a Correction Request now in the Java Correction Workbench and you should be able to copy its technical ID to use for the ``CR-Id:`` commit tag. If you hover the mouse over the correction request's ID, a small "copy" button will appear, easing your life.

-

-Once you have (for the Android case maybe "invented") the Correction Request's ID, you need to amend your latest commit that shall be pushed onto fa/rel-1.x:

-

- <pre>git commit --amend</pre>

-

-Add the ``CR-Id: ...`` line _immediately_ under the ``Change-Id:`` line and produce the new commit. Then push it to Gerrit using

-

- <pre>git push origin HEAD:refs/for/fa/rel-1.x</pre>

-

-For the following to succeed, make sure the commit you're pushing is the only one the Gerrit repository at ``origin`` hasn't seen yet because otherwise you'll have to review all commits starting from the first one unknown to Gerrit so far.

-

-The change will end up in your [list of Gerrit changes](https://git.wdf.sap.corp/#/dashboard/self). Press the ``Reply`` button located in the middle of the grey bar at the top of the page. You can then vote +2 and +1 for the change and post your review. After a short moment, the blue ``Submit`` button should appear. Press it, and the branch will be merged into ``fa/rel-1.x``. Final Assembly will need to be notified using a BCP ticket, such as a Handover ticket that can be created using [this link](https://support.wdf.sap.corp/sap/bc/dsi/ii/create_zini?sap-language=EN&system_id=BCV&short_description=Handover%20%3cPPMS%20Software%20Component%20Version%3e&priority=3&main_impact=A&category_label=XX-INT-NAAS-MOBILE&incident_description=Requesting%2520Development%2520to%2520Production%2520Handover%2520for%2520the%2520App%253A%250A%253CFull%2520App%2520Name%253E%250A%250AProgram%2520Repository%2520Link%253A%250AProgram%2520Name%253A%250APPMS%2520Software%2520Component%2520Version%2520Name%253A%250APlatform%253A%2520%253CAndroid%2520%252F%2520iOS%2520%252F%2520TFS%2520(Windows)%253E%250A%250AShipment%2520Channel(s)%253A%250A%255B%255D%2520Indirect%2520shipment%2520(promotion%2520to%2520Nexus%2520only)%250A%255B%255D%2520Apple%2520App%2520Store%250A%255B%255D%2520Google%2520Play%250A%255B%255D%2520Google%2520Chrome%2520Store%250A%255B%255D%2520Amazon%2520App%2520Store%250A%255B%255D%2520BlackBerry%2520World%250A%255B%255D%2520Windows%25208%2520Store%250A%255B%255D%2520Windows%2520Phone%2520Store%250A%255B%255D%2520SMP%2520-%2520Binary%250A%255B%255D%2520SMP%2520-%2520Source%2520Code%250A%250AiOS%2520%252F%2520Android%250A----------------%250ALink%2520to%2520Project%2520Portal%253A%250ASource%2520Code%2520Project%2520Path%253A%2520%253CPerforce%2520path%2520with%2520codeline%2520%252F%2520Git%2520Path%253E%250A%250AIf%2520project%2520is%2520using%2520the%2520LeanDI%2520environment%252C%2520code%2520signing%2520is%2520enabled%2520and%2520will%2520remain%2520enabled%2520for%2520All%2520Release%2520builds%253A%2520%253Cyes%2520%252F%2520no%253E%250A%250ATFS%2520(Windows)%250A-----------------%250ATeam%2520Project%2520Collection%253A%250ATeam%2520Project%253A%250AREL%2520Branch%2520Path%253A%250AREL%2520Build%2520Definition%2520Name%253A%250A%250ACode%2520Signing%2520Request%2520Ticket%2520(if%2520applicable)%253A%2520%253CBCP%2520Ticket%2520Number%253E%250A%250AList%2520of%2520build%2520Dependencies%253A%2520%253CNexus%2520artifacts%2520including%2520libraries%253E%250A%250ALink%2520to%2520completed%2520Metaman%2520Entry%2520(for%2520External%2520Stores)%253A%250A%250AContacts%2520%253CUser%2520IDs%253E%250AProduction%2520Project%2520Lead%253A%250AProduct%2520Owner%253A%250AResponsible%2520for%2520Handover%253A%250AResponsible%2520for%2520Technical%2520issues%252Fquestions%253A%250AOthers%253A) or an update ticket as explained [here](https://wiki.wdf.sap.corp/wiki/display/NAAS/Mobile+Patch+Releases) in section "Requesting an update."

-As a result of handling the request, Final Assembly will trigger builds on [http://dewdfms0059.wdf.sap.corp:8081/job/sapsailingcapture-fa-rel-1.0-fa-rel-1.0-GIT-REL-OD-COMPCOMP/](http://dewdfms0059.wdf.sap.corp:8081/job/sapsailingcapture-fa-rel-1.0-fa-rel-1.0-GIT-REL-OD-COMPCOMP/) and [http://dewdfms0059.wdf.sap.corp:8080/job/sapsailingcapture-fa-rel-1.0-fa-rel-1.0-GIT-REL-OD-COMPENTER/](http://dewdfms0059.wdf.sap.corp:8080/job/sapsailingcapture-fa-rel-1.0-fa-rel-1.0-GIT-REL-OD-COMPENTER/).
