First let me say I am South African and grew up there during the apartheid period. I still have family there and regularly return to visit. There is no dispute that there is a lot of violent crime, although most of the victims are coloured or black. The media usually only reports on the white victims of crime. What is in dispute is that the ANC is intent on genocide and is behind the attacks on farmers. That is nonsense. Further, the number of farmers murdered has been exaggerated. There are roughly sixty farmers murdered each year in comparison with more than 20,000 murders a year in the country. That is sixty too many, but it is not a genocide, it is victims of crime in a crime-ridden country.
Secondly, the ANC is a political party, it is not a party of tribes. It was founded in 1923 by the conservative, educated and religious professional classes of black South Africans, not by tribal leaders, to advocate for the rights of black South Africans. After apartheid became law, many whites also joined the ANC in opposition to apartheid.
Thirdly, your understanding of South African history has some gaps. The Dutch arrived in the seventeenth century and set up a halfway house in Cape Town for their ships travelling to India. There were already people living in the Cape who are commonly known as Hottentots, but more correctly as Khoisan. The coloured people of the Cape are largely descendants of liaisons between the Dutch and the Hottentots although there were other racial groups involved as well. The British arrived in the eighteenth century and as there was a war between Britain and Spain, and Holland was supporting Spain, they took over Cape Town and the area about it. After some time the Dutch living there resented the rule of the British and made their way up north. At the same time that all this was happening there were African people collectively known as Nguni coming down from East and Central Africa towards the south. It's quite a long story about how they became the various tribes we have today, but the main point is that these two movements of people met going in opposite directions at the Kei River, not too far from East London (South Africa). So if we are to speak of "invaders", it was the Dutch who "invaded" areas already occupied by the Nguni as they travelled further north and established the Dutch republics of the Free State and Transvaal.
